OIL-B RNER.

' Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed April 20. 1906. Serial No. 312,767.

To all whom it 'may concern:

Be it known that I, SAMUEL B. RAPPLEYE, a citizen of the United States,residing at Philadelphia., county of Philadelphia, and State ofPennsylvania, have invented a new and useful Improvement in Oil-Burners,of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, which form a part ofthis specification.

The object of my invention is to produce an oil burner in which the oil,at the point of burning' is thoroughly oxygenized while avoiding themixture, with the products of combustion, of inert gases that faileither to burn or to support combustion.

The invention also has for its object to produce a burner that is simplein construction, economical and efficient in operation, and that can beeasily taken apart for cleaning.

I will now describe a preferred embodiment of my invention.

' In the drawings: The figure represents a longitudinal sectional viewof my improved burner with its front end projecting beyond the wall of acombustion chamber.

The oil tube consists of a long straight section a open at the front ordischarge end, and a short curved section or elbow b threaded thereto.This tube may have an internal diameter of about l l/4 inches. Theclosed rear end of the oil tube has an orifice communicating with a cupr.

Surrounding the oil tube is a water tube c, threaded at its rear endonto the elbow of the oil tube, and thereby at its rear end, spacedfrom, and held in delinite relation to, the oil tube.

e is a cup at the rear of the water tube.

The water tube may be of an internal diameter of about two inches.

An air-and-water tube, composed of a front section f, a rear section g,and a short middle T section h, extends through the oil tube along itslongitudinal center, its rear end extending through an orifice in therear end of the oil-tube. The middle section h is provided with anupright inlet tube t' extending through,

and tapped into, the section h and the walls of the oil tube and watertube. The tube t' serves to hold the air-and-water tube in iixedrelation to the oil tube.

j is a cup at the upper end of tube t',

k is a cap for opening or closing the rear end of the air-and-watertube.

lwater is now dropped into the cup e.

dropped from the oil pipe into the cup r at the rear end of the oiltube. Heat is applied to the eil burner by inserting a heating mediumunderneath or Within the front end of the same. The cap c is turned toadmit air into the air-and-water tube. The oil, after it reaches theheated portion of the oil tube` is vaporized, and the oil vapors.uniting With the oxygen of the air emerging from the air-and-Water tube,is ignited. After the tubes of the burner become highly heated, Alterthe burner has become still more highly heated, the cap lc is turned tosluit off the admission of air to the rear of the air-and-water tube,and water is dropped into the cup j. The proportion of water to oil willvary with the particular application and situation of the burner,although ordinarily one part of water to live parts of oil will suffice.

The burner is especially applicable for heating boilers and hot airfurnaces. the front end of the burner being inserted into the fire boxso as to substantially exclude the admission of atmospheric air exceptsuch air as is admitted through the burner itself. In the drawings prepresents the front wall of the fire-box. The quantity of nitrogen gasset free by combustion is thus reduced to a minimum, while the hydrogengas is itself consumed and, with the burning constituents of the oil,produces an intense heat in the fire box.

The burner is very simple in construction, is easily operated, and maybe readily taken apart for cleaning.

Having noW fully described my invention, what I claim and desire toprotect by Letters Patent is:

l. An oil burner comprising an oil tube, a second tube within andsurrounded by the oil tube, a third tube outside the oil tube, waterreceiving cups connected respectively with the second and third tubes,and means to regulate the admission of air to the second tube.

2. An oil burner comprising' an oil tube havingl a turned up rear endthrough which oil is supplied, an inner tube within the oil tube, therear end of which extends through the rear wall of the oil tube, anouter' tube surrounding the horizontal part of the oil tube, means bywhich Water is supplied to the outer and inner tubes, and a cap on theprojecting rear end of the inner tube for regulating the admission oiair thereto.

An oil burner comprising an oil tube having a turned up rear end throughwhich oil is supplied, an inner tube within the oil tube, the rear endof which extends through the rear wall of the oil tube, an outer tubesurrounding the horizontal part of the oil tube, a water receiving inlettube communicating with the inner tube and extending through the wallsof the oil tube and outer tube, and a Water-re ceiving cup on the outertube.

4. An oil burner comprising an intermediate vaporizing tube means toadmit thereto oil, an inner tube extending longitudinally Within the oiltube, an outer tube within which the inner tube extends longitudinally,means to supply water to the inner and outer tubes, and means to supplyair to all the tubes.

An oil burner adapted for insertion and comprising an intermediatevaporizing admit oil to the vaporizing tube, an inner into a fire-boxtube, means to tube extending longitudinally within the vaporizing tube,an outer tube within which the intermediate tube extends longitudinally,said inner and outer tubes being open to the atmosphere at points backof their exit ends, means to supply an oxygen containing iiuid to boththe inner and outer tubes, whereby the oil is vaporized and oxygenizedbefore exit from the burner and before mixture with the oxygencontaining fluids emerging from the outer and inner tubes.

G. An oil burner adapted for insertion into a fire box and comprising anintermediate vaporizing tube, means to admit oil to the vaporizing tube,an inner tube extending longitudinally7 within the vaporizing tube, anouter tube Within which the intermediate tube extends longitudinally,and means to supply Water to the inner and outer tubes, all said tubesbeing open to the atmosphere at points back ot' their exit ends,

T. An oil burner adapted for insertion into a fire-box and comprising anintermediate vaporizing tube, means to admit oil to the vaporizing tube,an inner tube extending longitudinally within the vaporizing tube, anouter tube within which the intermediate tube extends longitudinally,

means to supply water to the inner and outer tubes, means to supply airin regulated quantities to at least one of thelast-named tubes,and'means to supply air to the oil-vaporizing tube.

8. An oil burner adapted for insertion into a fire-box. comprising anintermediate vaporizing tube having an oil inlet opening to theatmosphere, means to drip oil through tubes being open to the atmosphereat points back of their exit ends.

9. An oil burner adapted for insertion into a fire-box comprising avaporizing tube having an inlet openingr to the atmosphere, meanssupplying oil through said inlet to the vaporizing tube, and two tubesextending longitudinally of the vaporizing tube and arrangedconcentrically with respect thereto and with respect to each other, thetwo last-named tubes having inlets opening to the atmosphere, and meanssupplying water to one or both of the two last named tubes through itssaid inlet.

10. An oil burner adapted for insertion into a re-b0x comprising avaporizing tube having at one end an oil inlet opening to theatmosphere, and two tubes extending longitudinally of the vaporizingtube, one surrounding, and the other surrounded by, the vaporizing tube,each of the two last-mentioned tubes having water inlets opening to theatmosphere.

In testimony of which invention, I have hereunto set my hand, atPhiladelphia, on this 17th day of April, 1906.
